That's cool, I usually get 45-50, but my best was 57. I discovered that my bike is happiest on back roads about 50mph. My throttle impairment usually happens on the highway, I can't help it, it's the bike.
Could be related to that fleeting "--runaway throttle some of the baggers are talking 'bout"! I know that I am right handed and left footed, could also be a genetic thing...Ya jus never know...
